Embodiment Construction

[0017] The rotating crossbeam device proposed by the present invention is aimed at the problem that when the current mobile small football goal is not fixed, it is easy to pull the goal into the field and overturn and smash people when the two hands grasp the crossbeam and do the hanging swing action. The main structure of the rotating crossbeam device for preventing the football goal from being knocked down according to the present invention is as follows: figure 1 , figure 2 , image 3 , Figure 4 Shown, goalpost 1, sleeve pipe 2, rear inclined pipe 10, lower connecting pipe 14 and upper connecting pipe 15 are mutually welded and connected to form a goal frame, as figure 1 , image 3 shown.

[0018] The first embodiment of the present invention is to set the shaft seat 19 inside the two ends of the beam 3, and the inner end of the shaft 5 is inserted into the hole of the shaft seat 19 for interference connection; Bearing 17 is arranged on the outside of ring 18, and ...

Abstract

The invention belongs to the field of sports equipment, in particular to a rotary cross bar device for preventing knocking over a football goal. The rotary cross bar device is composed of a rotary cross bar assembly, a braking cross bar rotation assembly and a goal frame assembly. When a plug (9) is departed from an axle hole (21), both hands hold a cross bar (3) of the football goal, and the cross bar (3) can rotate downwards under the downward pressure, so that both hands holding the cross bar (3) can slip away from the cross bar (3), thereby basically preventing people from being hurt when people holds the football goal by both hands and knock over the goal by swinging without rotating the cross bar (3). During a football match, the plug (9) is inserted into the axle hole (21), so that the cross bar does not rotate, and at the moment, the goal has the same functions as the existing goal; and when the ball hits the cross bar (3) which can not rotate, the authenticity of resilience on the ball can not be influenced.

Description

technical field [0001] The invention belongs to the field of sports, in particular to a rotating crossbeam device used to prevent football goals from being knocked down. Background technique [0002] Football goals can be divided into different sizes. The big football goal is placed on a standard large field and fixedly connected to the ground, while the small football goal is placed on an indoor or outdoor small field. The current small field football competition rules have the following regulations on it: Two vertical goalposts and a horizontal beam connected to the top. The distance between the inside of the two goalposts is 3 meters, and the distance from the lower edge of the crossbeam to the ground is 2 meters. The width and thickness of the goalpost and crossbeam are both 8cm. The goal The depth of the net is the space distance from the inside of the goal post to the back, the upper end is at least 80cm, and the lower end is at least 100cm. The goal is movable, but i...
